Hi Kaliope. Welcome to NGA!
I agree that many supermarket and organic market fruits are fromF1 hybrid seed, and those may not "come true", especially if you save seeds for another generation.
But someone pointed out that there ARE some F1 crosses that stay pretty true to what you grew, at least for one generation.
You're already doing the best thing: try them and see!
(My go-to catalog for really fancy fruits and vegetables is Franchi ("Seeds of Italy"). They have some awesome-looking peppers! Or if you like experimenting with a wide variety, there is already one seed swap signing people up, and another about to start.)

If they are slugs or snails, and if that means that you started the seeds outdoors, are you in the Southern hemisphere? Or maybe somewhere tropical? My yard has gotten pretty chilly for peppers!
If yo have slugs or snails indoors, oh YUCK! Diluted ammonia is said to "dissolve" slug egg masses, FWIW.
For a soil drench, dilute supermarket ammonia by 1:10 or so. Probably follow up with water after a few hours.
If the ammonia will get onto leaves, don't make it much stronger than 1:16, and rinse with water soon. I really doubt that slugs would lay eggs on leaves, though. Only in the soil, I think.
